A bag contains Rs 150 paisa and 25 paisa coins in the ratio 8:9:11. If the total money in the bag is Rs. 366, how many Rs 25 paisa coins are there?

To determine the number of Rs 25 paisa coins, we'll start by analyzing the information given about the coins in the bag. The coins are in the ratios of 8:9:11, which suggests that if we let the common factor for these ratios be x, we can express the quantities of the coins as 8x for Rs 1.50 paisa coins, 9x for Rs 0.25 paisa coins, and 11x for Rs 0.05 paisa coins.

Next, we need to consider the total amount of money represented by these coin counts. Each Rs 1.50 paisa coin contributes Rs 1.50, each Rs 0.25 paisa coin contributes Rs 0.25, and each Rs 0.05 paisa coin contributes Rs 0.05. Thus, we can form the equation based on the total money of Rs 366:

[1.50(8x) + 0.25(9x) + 0.05(11x) = 366]

Calculating each term in the equation gives us:

• Rs 1.50 contributions: (1.50 \times 8x = 12x\
